IMPROVEMENT IN TREADLE-OPERATED CONFLUENT PUMPS.

Specification forming part of Letters Patent No. 194,377, dated August21, 1877 application led July 23, 1877.

To all 'whom it may concern:

' Be it known that I, RICHARD H. ScHENcK, of the city, county, and Stateof New York, have invented a new and Improved Pump, of which thefollowing is a specification:

In the accompanying drawing, Figure l represents a side elevation, Fig.2 a front elevation, partly in section, and Fig. 3 a plan View with topdetached, of my improved suction and force pump.

Similar letters of reference indicate corresponding parts.

The invention relates to an improved suction and force pump of effectiveconstruction, that is operated by the feet, and arranged to throw auniform stream of water; and it consists of two cylinders withalternately treadleacted pistons, that are connected by a chain or ropepassing over a central pulley between the same,each stroke of thepistons producing the induction and eduction of the water, in connectionwith suitable valves and channels connecting the cylinders, suction anddischarge pipes.

VReferring to the drawing, A A are two pump-cylinders, which are mountedon a suitable frame, B, being connected at the base, by suitably-valvedchannels, with the suction and discharge pipes, and at the top by asemicircularconnectioinA. rEhe cylinders A A have pistons C, that areoperated by treadles D, which are jointed by pivot-rods a to thepiston-rods, the pistons being connected by a chain or rope, C', thatextends from the upper part of one piston over a grooved disk or pulley,b,.to the other piston. The shaft of the pulley b turns in bearings of alateral stay or brace-piece, d, connecting the upper ends of thecylinders. The treadles are alternately operated by the feet, the bodybeing kept in steady position by means of a hand rail or rest, E,secured to the supporting-frame, and adjustable to different heightsthereon.

The stroke of each treadle produces the lowering of one piston and theraising ofthe other piston, the pistons exerting thereby,simultaneously, a suction and force action, so as to draw in the waterby the induction-pipe and discharge it by the eduction-pipe. Theeduction-pipe takes up the water in the airchamber F and passes out atthe top of the same, the air in the air-chamber regulating the flow ofWater and keeping it up in uniform manner. l i

The pump can be made of small height, with short strokes of thetreadles, so as to be worked with great facilityandlittleeffort, and beused as an effective garden and street pump, lire-extinguisher, and forother purposes.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- In a suction and force pump, the combinationof two cylinders, connected with valved induction and eduction pipes,with alternately. I

voperated and treadle-acted pistons, connected by a top cord or chainpassing over a guidepulley from one piston to the other, substantiallyin the manner described, and for the purpose specified.

RICHARD H. SGHENCK.
